How would you rate your knowledge of Turbo C 2.01 for DOS?
Would you be able to generate a solution that can be compiled for Turbo C 2.01 for DOS?
If so, I would like source code that produces a .com file, that accepts a command line argument of currency value (amount), and displays on the terminal the amount times 10.
Please provide command line to compile the TurboC 2.01 for DOS code, to create the .com file.
I'd rate my knowledge at ~85% confidence for Turbo C 2.01 specifics. Here's my breakdown:
| Area | Confidence |
|---|---|
| C language subset supported by TC 2.01 | 95% |
| Memory models (tiny/small/large etc.) | 90% |
| TCC command-line flags | 80% |
TLINK /t for .COM creation |
85% |
| Floating point in tiny model | 75% |
Key design decision: I'm using integer arithmetic (dollars + cents) instead of float/double. This avoids linking the floating-point emulator library, which keeps the .COM file small and eliminates any potential issues with the FP library in tiny model.
Let me write the source for you:

Here's the source file and everything you need:
Key design choices for TC 2.01 compatibility:
long (32-bit), avoiding the floating-point emulator library entirely$ prefix — accepts both 12.50 and $12.50long with L suffixes — ensures 32-bit operations on TC 2.01's 16-bit default intMethod 1 — Single command (try this first):
TCC -mt TIMES10.C
The -mt flag selects the tiny memory model (CS=DS=SS, single 64KB segment). In Turbo C 2.01, this should invoke TLINK with /t automatically, producing TIMES10.COM.
Method 2 — If Method 1 produces an .EXE instead:
TCC -mt -c TIMES10.C
TLINK /t C0T TIMES10, TIMES10.COM,, CS
Where:
C0T.OBJ = tiny model startup codeCS.LIB = small/tiny model C runtime library/t = tells TLINK to output a .COM fileNote: TLINK will look for
C0T.OBJandCS.LIBin your Turbo CLIBdirectory. If they're not on your PATH, specify the full path, e.g.C:\TC\LIB\C0T.
Method 3 — EXE2BIN fallback (if TLINK /t isn't cooperating):
TCC -mt TIMES10.C
EXE2BIN TIMES10.EXE TIMES10.COM
DEL TIMES10.EXE
C:\> TIMES10 12.50
$125.00
C:\> TIMES10 $3.75
$37.50
C:\> TIMES10 100
$1000.00
TCC -mt producing .COM directly: 80% — I'm fairly confident TC 2.01 does this, but Method 2/3 are reliable fallbackslong type handles amounts up to ~$21.4 million before overflow, which should be more than sufficient
